PXW-FS5 Firmware Version 4.0 with HDR and 2000ISO for S-Log

Sony have today released firmware version 4.0 for the PXW-FS5. This firmware adds the ability to directly output Hybrid Log Gamma via picture profile 10 for an instant HDR workflow. It also allows you to set the base ISO for S-log to 2000 ISO.

There are new low ISO settings for all of the profiles, not just Slog. For instance, Standard’s new low ISO is 800. Since the pre V4 low ISO was 1000, and the corresponding gain was 0db, does the new low of 800 correspond to 0db, or are they gaining down to -3db? The gain settings haven’t changed and are still 0, +3, etc. Thanks.

It’s not a gain change as such. I suspect Sony have altered the way the way the analog to digital converters on the sensor are working or shifted the digital processing range used. So not quite the same as a gain shift, so no loss of dynamic range as would normally be associated with negative gain.

Thank you. So do we have to wait a correction from Adobe to use 2020 in Premiere or is it ok to use 709? The color render seems not the same with HLG3 for instance. By the way, what do you think about HDR? I ran some tests and it looks very great, very smooth in highlights.

I would continue to shoot at +1.5EV as the dynamic range, headroom and shadow range have not changed so you will continue to see an improvement in mid range and shadow reproduction by shooting a bit bright. Now you will have even less noise than you had before.

Dear Alister. According to you, is there an benefit in using HDR instead of S-Log for a cinema style short film edited with Premiere, colored in Da Vinci and released on a Blu-ray or a DCP? Is there a gain in the softness of highlights and, for example, with skin tone?
Thanks a lot,
Ben
